Sec.  251.23  Experimental areas and research natural areas.

    The Chief of the Forest Service shall establish and permanently 
record a series of areas on National Forest land to be known as 
experimental forests or experimental ranges, sufficient in number and 
size to provide adequately for the research necessary to serve as a 
basis for the management of forest and range land in each forest region. 
Also, when appropriate, the Chief shall establish a series of research 
natural areas, sufficient in number and size to illustrate adequately or 
typify for research or educational purposes, the important forest and 
range types in each forest region, as well as other plant communities 
that have special or unique characteristics of scientific interest and 
importance. Research Natural Areas will be retained in a virgin or 
unmodified condition except where measures are required to maintain a 
plant community which the area is intended to represent. Within areas 
designated by this regulation, occupancy under a special-use permit 
shall not be allowed, nor the construction of permanent improvements 
permitted except improvements required in connection with their 
experimental use, unless authorized by the Chief of the Forest Service.
